The tightener represented in Figs. 3 and t is or may be of theconstruction set forth in my revious specification forming part of anapplication Serial N 0. 481201, filed- March 3, 1909, (Letters PatentNo. 925990, dated June 22, 1909) and the parts re resented in Figs. 8and 9 are the slotted sha t of the tool, represented at (Z, a cross barof the frame be neath said shaft,represented at c, and a cross bar atthe front edge of the frame, repre' I tightening operation. 'Otherwisethe tool may be of the con truction set forth in said previousspecification forming part of'said' application Serial No. 4.81201,(Patent No. {525990) or of any suitable known or improved construction.

The improved seal press, shown by Figs. 8 to 12, inclusive, in.connection with said Figs. 2, 4, 5 and 6, is characterized by a base, g,of novel construction having lateral edges, 1 and 2, of sufficient depthfor the sealing and seal-releasing operations hereinafter described, aflat bottom, 3,- and a free front edge; 4, tapered as shown, with itsthin extremity in the plane of said bottom, a central hole, 5, extendingvertically through the bottom, and a concavity or depression, 6, in

the top of the base, between said lateral edges 1 and 2 and adjacent tosaid free edge 4, within which said hole is located. Said base 9is'furthcr provided with a gage stop,

7, adapted to embrace the seal part a, and

undercut front ends, Sand 9, toengage the inner edge of the box strapbwhen the latter is in eiieetive position within the seal press as inFig. 4. This gage step may be formed by an inserted circular piecethrough which a said hole 0 extends, as shown in the drawings, or maybeintegral With the base cast: ing, as preferred. A pair of cheeks, h and'4 supported by said base 9 and preferably integral therewith, arelocated behind said gage stop 7 with their front ends overhanging saiddepression 6; and a rnovable memt, ,7', rrying a punching bit erypunch,la,

at its free end, iSPlVOlZCl between said cheeks by a ivot, Z, at itsrear end parallel with .said ree edge 4: of the base, said punch itbeing alined with said hole-5 in the base in the depressed position ofthemovable member represented in Fig. 5 and by dotted lines in Fig. .8.Said movable member j and piinch In may conveniently be cut from rodsteel.

. A spring, m, Fig. 8 interposed betweenthe base and puncltcarryingmovable member vj, renders the latter normally spring elevated, with thepunch in its position represented in Figs. 1, (3 and 10, and in fulllines in Fig. 8. The specific spring represented is of rubber. i

As means for depressing the movable member j, in the sealing operation,a hand lever, a, is pivotedbetween the overhanging front ends ofthecheeks 172, and by a horizontal pivot, 0, parallel with said pivot Z,andis constructed with the customary canny, adjacent to its pivot, tointeract with the free end of the movable member substantially in linewith the punch. 7c. in the sealing operation, illustrated by Figs. 3 to6 inclusive, after threading both ends 1 and 2 of the box strap 6through the seal part a, the under end 1 is preliminarily fastened as bydriving the spur 5 on the'cross bar 6 of the tightener therethrough, andthe upper end 9. is athiched to the shaft (5 of the tightener, and.drawn beneath its cross barf by working the tool, as represented bythear row a in Fig. 3, until the be); strap is under the desired tension.The free edge 4: of the base g of the seal press is then inserted edgewise beneath the seal part a, and the oven. lapped ends of the box strapb embraced. v thereby are located therewith beneath the 95 punch 75by'nicans of the gage, stop 7. A 7 single movement of the hand-lever nthen dopresses the punch until the seal part is arrested by the bottomof the depression 0,

and the )unch is driven throu h the seal part and box strap as in Fig.5. .In this operation downtnrned portions oi themetal of the top andbottom of the seal part and of bothbox strap ends are interlocked witheach other as represented at 6' in Fig. 7, 'and an effectivescalmgoperation is thus completed. A return movement of the hand -levcrit permits the punclrcarrying movablemembcr j to be reelevated by thespring 11?.

.so as to free the punch .4: from the seal part a, and. the resiliencyof the box strap 1), owing to the elevated supports of the box strap atthe lateral edges 1 and 2, reelevates. the seal part (4 within thedepression (3 so.

to free said interlocked portions 6 from'llh the hole 5 of the base 5/,as in Fig. 6, and; thuspermit the seal press to be Withdrawn-.--edgewise from the sealed box strap. v

' A single sealed box strap may in the above manner be located betweentheends ofthe box as in Fig. 1, or between the sidesfort between thebottom and top of the box,as'

there is no seal nailtobe driven through the cover or like boxpart intothe ends.) 'lhei box-strap and seal part may also, ot Conrad/T beotherwise arrarwcd and may be du )li-'- eatcd or multiplied 1t desired.I

The several parts oi the improved seal--v press obviously admit oiconsiderable var1a- .tion in shape, including thc point of'tho v punchk; metallic spring of coiled wire or tint metal may take the place ofthe rubber spring m; and other like modifications will suggestthemselves to those skilled in the art.

Having thus described said. improvement, I claim my invention and desireto patent under this specification:

1. seal pressfor fastening metallic box )5 under tension by means ofnailless metallic box seals, such press having, in combination, ahorizontal base portion constructed with a fiat bottom adapted to restsolidly upon the box and with a tapered free edge'insertible edgewisebeneath a seal part embracing the overlappe' ends of a be strap undertension, ai'idprovided with a hole adapted to admit downwardlyprojecting fastening portions of the seal part and box strap and a stopgage for locating the seal part above the hole, a superjacent downwardlymovable member carrying punch alined with said hole in its depressedposition, and means for operating said movable member to complete theseal.

2. A seal press for fastening metallic box straps under tension bynieans'of nailless metallic box seals, such press having, incombination, a horizontal base portion inedgewise beneath a seal partcinbrucing the overlapped ends of box strap under tension and providedwith a hole adapted to admit downwardly projecting fastening portions ofthe seal part and box strap, a superja-cent downwardly movable membercarrying a punch alined with said iole in its depressed position, andmeans for operating said movable member to complete the seal, said baseportion being flat-bottomed and, constructed with a tapered free edgehaving its thin extremity in the plane of the bottom of the base.

3. A. seal press for fastening metallic box straps under tension bymeans of nailless metallic box seals, such press having, in combinationwith a suitable punch and means for operating the same, a horizontalbase portion constructed with a free edge, insertible edgewise beneath aseal part embracing the overlapped ends of a box strap under tension,and provided with a central hole within a depression adjacent to saidtree ed 'e between relativel" elevated lateral edges, whereby abox-strop under tension supported at said lateral edges is adapted tofree the fastening portions of the rtill j' art from said hole by itsown resilience after the sealing operation.

-l-.
